I have used the same laptop for 18 months (when it was newly purchased). I always shut it down and start it up cleanly for my Zwift session. However the time for Zwift to load varies immensely from between 90 seconds to over 4 minutes last night.
I have fast broadband and do not have problems in-game or with any other application I run.

It is nothing to do with any updates .

What causes this variability. To sit there and wait for 4 months to eventually see ‘logging in’ is immensely frustrating, especially when you are rushing to start an event.

John Hallas, you don’t say how long you wait after booting your computer until starting Zwift but my guess is that if you start Zwift right after you boot the variability is caused by other things that might happen at system startup such as programs checking for updates, applying updates and patches, etc. Are you using an SSD?

I have the same issues. I have been using it since beta and it’s gotta worse. I have fiber and a gaming machine that only runs this application. I reboot fresh every morning, let it get running, launch Zwift and wait and wait.

Sorry but Zwift is becoming a training frustration. The trainer (NEO) does adjust accordingly now. Especially on the New York course. Unless I have gotta really strong for a 15% gradient. (Yes I have it set to 100%).

I see the same thing too, on Windows 10. This is without a reboot, it seems to happen most times I start Zwift but not always. It’s only Zwift, other applications start right away. The symptom is that Zwift shows no signs of starting to launch for several minutes after starting the app - i.e. this is a delay before the launching splash screen shows up. Once the splash screen comes up, launch seems to be pretty normal.

Yip have the same issue. SSD, 32Gb Ram, GTX 1070 8G, 40Mb fibre link, Win10 and zwift loading time is like watching paint dry. And like some others commented, it seems to be getting worse. I would sometimes start zwift and then start to get dressed. I’m almost always finished first.

So I reached out to support about the slow load, and shutdown times and send full machine dxdiag and network speed tests. Seem like the platform has met it’s match since they have not responded yet making support slower than the app. Time is definitely here for more competition in this arena. Zwift is getting way to complacent.

As far as I can tell the slowdown started with the update before last. It now takes Zwift around 30s to 40s to go from “Let’s Go” to “Logging In”. I’ve noticed recently that the Android app no longer connects fully either. I can sometimes see my current workout numbers on the profile page, but it’s no longer possible to control the ride from a phone. It seems they’re in a phase of introducing major bugs into the software.
